Jeremy sells pencils. his daily sales have been linear. jeremy sold 20 pencils on the first day, 23 pencils on the second day, and 26 pencils on the third day. a function can model jeremy’s sequence. what is the slope of that function?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
